    PROPER Optical Propagation Library

    Routines for wavefront propagation in IDL, Matlab, and Python

    PROPER is a library of routines for the propagation of wavefronts through an optical system using Fourier-based methods. It was developed at the Jet Propulsion Laboratory for modeling stellar coronagraphs, but it can be applied to other optical systems were diffraction propagation is of concern. It is currently available for IDL (Interactive Data Language), Matlab and Python (3.x). It includes routines for generating complex apertures and obscurations and aberrations (Zernike & PSD-defined). It includes a model of a deformable mirror for wavefront control. The routines perform near and far field propagation with automatic selection of propagators. The latest version is v3.3.1 (IDL & Matlab) and v3.3.4 (Python). Please report any bugs using the Tickets tab.

    DarkLight Cover/Calibrator

    DarkLight Cover/Calibrator

    DIY project to build a cover, flat panel or combo flip-flat panel

    The DarkLight Cover/Calibrator (DLC) is a DIY project to build a motorized telescope cover, flat panel, or a combination flip-flat system. Its modular design supports various setups: a 12V light panel without a servo for a wall-mounted calibration panel, a servo-only cover for sky flats, or both integrated into a flip-flat mechanism. The DLC also includes optional dew heating to reduce extra equipment and cabling. With available drivers, it works with ASCOM or INDI. We’re excited to announce that the DarkLight Cover Calibrator project has officially moved to GitHub! 🔗 New GitHub Repository: 👉 https://github.com/10thTeeAstronomy/DarkLight_CoverCalibrator © Nathan Woelfle 2025.

    General data-reduction tool for fiber-fed integral-field spectrographs

    p3d is a general data-reduction tool for use with fiber-fed integral-field spectrographs (IFSs); although, the spectrum viewer works with spectrum data cubes of any origin. The tool is built about the proprietary software IDL (Harris/EXELIS; see http://www.harrisgeospatial.com), but can be used without any license. Most slowly running loops are implemented in parallelized C (OpenMP).
